According to a Pew Research Center nationwide telephone survey of adults conducted between March 15 and April 24, 2011, 55% of college graduates said that college education prepared them for a job (Time, May 30, 2011). Suppose this result was true of all college graduates at that time. In a recent sample of 2000 college graduates, 59% said that college education prepared them for a job. Is there significant evidence at a 2% significance level to conclude that the current percentage of all college graduates who will say that college education prepared them for a job is different from 55%? Use both the p-value and the critical-value approaches. Round your answers for the observed value of z and the critical value of z to two decimal places, and the p-value to four decimal places. Enter the critical values in increasing order. zobserved =Enter you answer; z_observed p-value =Enter you answer; p-value Critical values: Enter you answer; Critical value 1 and Enter you answer; Critical value 2
